How use the library to edit the repository

[juanitourquiza]

I used the library to create and is working perfectly but when I use the library to modify the register replaces every image.

afuConfig = {
    uploadAPI: {
      url: `${environment.images}`
    },
    theme: "dragNDrop",
    multiple: true,
    formatsAllowed: ".jpg,.png,.jpeg",
    maxSize: 10,
    autoUpload: false,
    replaceTexts: {
      selectFileBtn: 'Select Files',
      resetBtn: 'Reset',
      uploadBtn: 'Update Images',
      dragNDropBox: 'Drag N Drop',
      attachPinBtn: 'Attach Files...',
      afterUploadMsg_success: 'Successfully Uploaded !',
      afterUploadMsg_error: 'Upload Failed !',
      sizeLimit: 'Size Limit'
    }
  };

DocUpload(evt: any){
    this.project.imagenes = evt.body.data;
    this.generalService.loadUser().subscribe(
      (res: any) => {
        this.user = res.data.id;
        if(this.project.title == '' || this.project.clave == ''){
          alert('Please fill all the fields');
          return;
        }
        this.generalService.updateProject(this.project, this.idProject, this.project.imagenes).subscribe((results: any) => {
          alert('You updated successful project');
          this.router.navigate(['../dashboard']);
        });
      },
      data => {
        this.errorMessage = data.error.errors[0].message;
        alert(this.errorMessage);
        this.router.navigate(["/"]);
      }
    );
  }

What is the problem?
